Application filed July 1;

have invented certain new and useful Improvements in Roasting Machines; and I do ereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same. 7

ihe objects of this invention are to provide means in connection with a roasting machine for removing undesirable matter from the product being roasted; ix) provide means for removing dirt and dust from the product as said product is introduced into the roaster; to employ a suction system for this purpose; to permit regulation of the intensity of the suction so as to avoid removal of any of the product to provide means for red or empty units of the product; to employ the same suction system for this purpose as used for initial removal of the dirt or dust; to provide means for discharging the empty or shriveled units and prevent the same from clogging the suction system; to enable the suction connections to be removed or gotten out of the way when not in use; to secure simplicity of construction and operation and to obtain other advantages and results as may be brought out in the following description. Referring to the accompanying drawings in which like numerals of reference indicate similar parts throughout the several-views.

Figure 1 is a side elevation of a roasting machine with my inventionapplied thereto;

Figure 2 is a. sectional view of a portion of the suction screen therein;

Figures 3 and 5 are elevations of the suction pipe showing the hinged attachment of the branch pipe.

In the specific embodiment of the inven tion, illustrated in said drawings, reference numeral Lindicates in general the roasting machine in which the product, such as pispipe showing the damper and re 7 is a perspective view of the head 1822. Serial No. 572,888.

tachio nuts, are to be roasted. This roaster contains the usual rotating drum. and "eat producing elements (not shown) common to masters of this nature. On the top of the roaster is a suction connection 2 leading to a main suction pipe 3 by means of which steam produced in the process of roasting may be carried off. At the front ofthe roaster is an opening 4 through which the product is introduced into and removed from the roaster drum. A hinged closure 5 is'provided at this opening 4; arranged to swing downwardl and operate as a shute for introducing t e product into the roaster.

The roduct is referably introduced first into a opper 6 a ove the opening a by any suitable means; Except as forsuch opening as necessary for introductionof the product into this hopper, the same is preferably closed so that dustresulting from introduction of the product will not escape. From the closed top 7 of said hppper, leads a suction' pipe 8 to the main suction pipe 3, and a sufiicient suction is employed for removing the dirt and dust from the product as it enters the hopper. In order toregulate the suction, I preferably provide a damper 9 in the pipe 8 betweenthe main suction pipe 3 and the hopper, and this damper may be turned to more or less cut off the interior passage of said pipe to obtain just enough suction to carry 0H the dirt without carrying any of theproduct away. The bottom of the hopper 6 is provided with a stem by means of which the'opening to a opper shute 11 may be "opened or closed. This hopperv shute may be turned so that its lower end is directed into 0 ening 4 of the roaster, I

or may be turned so t e lower end is directed away from the roaster so as not to interfere with free access to said ope It is to be understood that in o eration, t ev roduct is introduced into the opper 6 wit the suction removing the dirt and dust'while the product is'being introduced, and the hopper shute 11 is directed into the roaster with the gate 10 open so the product will pass into the roaster for treatment. When a suficient quantity of the product is introduced into the roaster, the gate 10 of the hopper is closed and the hoppef shute l1 removed from the opening 4 of the roaster, at which time the roasting process is started and is continued until the product is sufiiciently treated. W

For use duringtreatnient or roasting of desired, a damper 17 stand-pipe 12, but will tilt the product, I provide means for removal of empty units of the product, and for convenience employ the suction system also for this purpose. Preferably this removal of the empty units is accomplished by means separate from the hopper and shute 11, but obviously if found more desirable the same means might be utilized. As shown, I provide a stand-pipe 12 connected at its upper end to. the main suction pipe 3, and provided at its lower end with a suitable closure 13 which may be retained shut when desired or opened as becomes necessary or desirable. Intermediate the ends of said standipe is a branch-pipe 14 hinged as at 15 so it may be swung with its lower end in proximity to the shute 5. Above the introduction of this branch-pipe 14 in the stand-pipe 12 is a screen 16 for preventing any of the product units from passing into the main vacuum pipe 3 or from passing out of the vertically arranged portion of the stand-pipe. If so Stand-pipe for regulating the intensity of the suction utilized in connection with this part of the system. In operation; the lower end of the branch-pipe 14 is arranged to be in close proximity with the product as it passes the opening 4 during agitationv with in the roaster, and the intensity of the suction is regulated to act only upon shriveled or empty units of the product, the good units being heavy enough to remain in the roaster unaffected by the suction. The empty or otherwise undesirable units are drawn up the branch-pipe 14 and into the j e prevented from going further by virtue of screen 16. When the stand-pipe 12 becomes full or clogged, opening of closure 13 at the bottom thereof will permit the empty shells to drop out of the stand-pipe into a suitable receptacle 18, after which the closure 13 is closed so the suction will still function upon the product in the roaster. In this way, it will be seen that both dirt andundesirable units of the product are, removed from the said product so the same is improved in appearance and clgiiracter and increasingly edible and sala e.

As shown in the drawings, it is preferable to provide a suitable head 19 on branchpipe' 14 which may be inserted in the opening 4 of the roaster and substantially fill the same. This head 19 preferably is box like in shape and pipe 14 enters the same adjacent one side and extends a distance toward the inner head as shown at 20, with a flange 21 fiaring toward the other side of the said box like structure so as to have a tendency to deflect the units of the product into the inner end 20 of said branch-pipe '14. The outer end of said box e structure, between the branchipe 14 and the side wall furthest there ram is may be provided in the 9 mecca? provided with a hand hole 22 with suitable closure 23 by means of which the operator may view the interior of the roaster while the device is in place or may reach in and obtain some of the product for testing or other purposes. In order to positively pass the product close to the end 20 of the branch-pipe, aI preferably provide a deflector 24 supported b suita 1e brackets 25 at a spaced distance rom the inner end of the box like structure, said deflector sloping toward the branch-pipe. In this way, the product is brought within suction and the empty shells'will be thereby withdrawn.

Obviousl detail changes and modifications may e made in the construction and use of my improved invention, and I do not wish to be understood as restricting myself to the exact structure shown exce t as required by the following claims w en construed in the light of the prior art.
